Fiat will be replaced by crypto currency but i dont think it will be bitcoin. Government want to control everything and even fiat money , bitcoin cant control by the governement so they will create thier own and will use blockchain technology to make a new way of payment before fiat currency fall.
Sure
the government cannot control Cryptocurrency but the Government is likely to Crash too
Really?So you are saying that no government can't control crypto mining and trading?
What if USA and EU ban crypto mining and trading?What happens then?
